The character of the neighborhoods varies significantly from one to another and includes everything from large skyscrapers to houses from the late 19th century to modern, suburban-style developments. Generally, the neighborhoods closest to the city center are denser, older and contain more brick building material. Many neighborhoods away from the city center were developed after World War II, and are built with more modern materials and style. Some of the neighborhoods even farther from the city center, or recently redeveloped parcels anywhere in the city, have either very suburban characteristics or are new urbanist developments that attempt to recreate the feel of older neighborhoods. Most neighborhoods contain parks or other features that are the focal point of the neighborhood.[citation needed]

In the closing years of the 19th century Don Melchor de Concha y Toro discovered that his most treasured wines had been pilfered from the “casillero” (cellar) beneath his family home.

Today, the original Concha y Toro family estate, complete with its Devil’s Cellar, is Chile’s leading tourist destination!
